IMPROVMEN T IISI' STQVE-PIPE SHELVES.

The seheaule referred to m'nneae'nrters Patent and making pm ef thesame..

To all whom it may concern:

Be it known that we, CHARLES BAGLEY f and OHnnnEs E., Mason, of Elgin,inthe county of Kane,- and State of Illinois', have-inventedaWarmingfShelf,

to be attachedl toa Stove-Ripe; and-We do declare that the following isafull, clear, and; enact description thereof, reference being. had .tothe accompanying drawings, making part of this specification, in which-Figure l is a bottom view;

l Figure 2, an inside Etop view, the upper plate and sidevbeing removed;f

' Figure 3 is a side view, a portion being cut away;

- Figures 4, A5, 6, details of opening;

f Figures 7. and- 8, details of drying-attachment;

Figure 9, a top View; Figure' 10, a side view, with part removed, butshowing damperr.

Theobject of our `invention is 4to construct a shelf,

to be attached to a stove-pipe, in -sucha.manner that the shelf shall beheated by the heat which passes fromt-he stove int'othe pipe, and alsooperate as a radiator.

To enable others skilled -in theart'to make and use our invention, weproceed todescribe its construction and operation.

In the drawings- A represents the top plate or piece, and B, the bottomor under piecepf my shelf. i

D is the side. l

C, a deflector, placed between 'A and B, and is not quite as large asthese, a space being left between` its edge and the side D for'thepassage of the smoke, and other products of combustion, through theshelf. This deectorO is'supported in place by theposts c.

In the centre ofthe detlector, I providev an opening,

so that the'smoke may, if desired, be caused' to pass directly throughthe deector instead of over its edge, l

which opening may, when desired, be closed by a suitable dampen i Asshown `in the drawings, therearethree small openingsat or near thecentre of thexdefleetor, made by cutting-the material onthree sides ofthe opening, and bendingup the parts so partially cut'out, thus formingwin gs or small defleetors, d, the eect of which is partially to checkthe` direct current of theproducts These ope-ningscan be.closed by aregister or darnper, n, operated(as shown) by the pin e moving in theslot j, and in a corresponding slot in the ange or' colproper point. l

The red lines in ig.`2 show the movement of the damper and thin vpieceh. The damper is shown closed- `in both figs.` 1 and v2.

The shelf is provided with two pipe-connections, a

b, by means of which it is-connected to the pipe of the.

stove,'surrounding the same.

j is a flange, extending from a, and secured to thebottom B.

t', is an opening, closed by a" cover or slide, k, through which sootwhich accumulates inthe shelf may be removed.

v'Io the bottom B we connect a device, m, to which arms may be attached,upon which to hang articles to bedried.

.For ordinary purposes we make the shelfoval, about. eighteen inches indiameter, or across one way, and about twofeet across the other way, andabout three inches thick, leaving a space `of about one and a half inchbetween the deector C and each plate A B.

We make tbeshelf of sheet-iron.

For the purpose of more perfectly controlling and regulating thedraught, we .place a circular damper vbetween the dee'ctor O and the topplate A, and surroundingan'd enclosing the damper nl This circulardamper is shown in gs. 2 and "10, aud is constructed as follows A bandor hoop of metal i'ssecured between O and A, outside of\ the damper nand wings d, inwhich bandare several holes. Fitting somewhat looselyover and around this band, is another band or hoop, fr, also providedwith the same number of holes as are placed in the rst-mentioned band,and so placed that the holes in one may be brought opposite the holes inthe other. vThe lon-ter band lr,'bein g loosely fitted, as aforesaid,may be moved partially around by means ofthe rod s, connected theretoand passing through the side D, or in some other suitable manner,therebyclosing or covering the opening in the fixed band.

One of--these bands is to be provided with a stop,

so placed as toeontrol the movement of the outer' band o', so thatinopening and closing the'OpenDgs in the fixed band, it will not be movedbeyond the When the damper nis closed, the draught through the pipe may-be regulated and controlled by means-of the damper or register 'r, theopenings therein being partially closed to the extent which may be'desirable',

depending on the state of the atmosphere and other circumstances.

` When both dampers are opened there will be a direct draught throughthe damper n., while, at the :sanne time,fa portion of the'heatpassingol" will be carried through all parts of '.the shelf.

Thisshelf has been, found to be afjlvery useful attachment, especiallyto dining-room stoves, as upon it quite a number of varticles may beplaced which it is desirable to have warmed or kept warm; and, at

the sanie time, it is an excellent radiator, as, from its Y peculiarconstruction. and compact form, a large portion ofthe heat whichpassesinto it must be radiated therefrom.

In use, the shelf is placed horizontally upon the pipe of the stove,beirg connected thereto at and b.

The courseof the vproducts of combustion will b'e understood from theabove description'.

Having'thus fully described our invention,

What we V claim as'new, 'and desire'to secure by Letters Patent, is asfollows:

` 1. The sbeliA', when'providedwith'aheating-cham;

ber beneath it, constructed substantially` as and for.

the purposes specified'.
